Are you thinking of something else? The patch hasn't been committed
AFAICS.

Here is *another* patch, along the lines of what Matt suggested - the
changes are only to sleepq_broadcast. Seems to work. This patch includes
comment and doc changes to kern_synch and scheduler.9 indicating that
setrunnable() no longer awakens the scheduler.

I was not sure whether wchan != &proc0 should be added to the 'if'
around the wakeup. I don't think it is needed.
